| The pleated skirt is one of the styles of women’s daily wear.Its wearing shape influenced by the fabric properties and the proportion of the pleat,and the change of any one of the parameters will bring different modeling effects.Studying on the relationship between the appearance of pleated skirt and fabric properties and fold ratio Scientifically and Systematically is the key to enterprises to produce beautiful pleated skirts.Therefore,this subject selected pleated skirts produced by document[1],then objective evaluation index of pleated skirt modeling was extracted through shooting method and three dimensional scanning method and objective evaluation and subjective evaluation of pleated skirt was carried on.Then the influence of fabric properties and pleated proportion on the pleated skirt appearance was studied using correlation analysis and regression analysis.And then the best proportion of pleated skirt regression prediction model based on fabric properties was established.The main contents and conclusions of this paper are summarized as follows:Chapter 1:Introduction.The research background,purpose and significance of this subject were expounded.The status of the related research of pleat modeling,objective evaluation of the appearance of dress.the relationship between dress style and fabric properties were detailed analyzed.Then the subject introduced research contents,innovation points and difficulties,research methods and technical routes.Chapter 2:The Evaluation of the Appearance of Pleated Skirt.The subject introduced the determination and extraction objective evaluation index of appearance of skirt and data analysis of Objective evaluation specifically.15 two-dimensional objective indexes of pleated skirts were extracted by shooting method and 13 three-dimensional objective indexes of pleated skirts were extracted by three-dimensional scanning method,a total of 28 index parameters.And then the subject extracted 5 subjective evaluation index by expert interview,including the waist-to-buttocks fitting,pleated uniformity,fluffy degree,A sense of skirt profile and overall aesthetic extent.And subjective evaluation was conducted.After that,3 objective evaluation factors of the appearance of pleated skirt were obtained by principal component analysis according to the correlation of subjective and objective evaluation,and they were area width factor,waist pleated characteristic factor,bottom ripple characteristic factor,Then the subject took the objective evaluation factor score as the explanatory variable and the overall aesthetic degree as the explanatory variable,a linear regression prediction model of the overall aesthetic appearance of the pleated skirt was established.Chapter 3:Clustering Analysis of Pleated Skirts.According to the results of the subjective evaluation and factor scores of objective evaluation,the skirt was divided into 4 types,they were the best type of aesthetics(the most uniform pleats,the most suitable waist,the weakest type A),the better aesthetics(more uniform pleats,more fit waist,stronger A-shape)and beautiful appearance Degree of general(less uniform pleated,the waist is less fit,A-type sense of weakness),the overall shape of aesthetics less class(irregular pleat,waist fit the worst,A sense of the strongest);Pleated The subjective evaluation index of the best aesthetics of skirts showed a score ranging from 3.77 to 4.11 for the waist-to-hip fit,4.19 to 4.40 for the fold uniformity,and 2.09 to 2.72 for the outline shape type A sense of the overall aesthetic The scores ranged from 3.61 to 3.96.The scores of the objective evaluation factors ranged from-1.1342 to-0.1896,and the scores of the morphological characteristics of the waist fold ranged from-1.0968 to-0.3479.The scores of the characteristic sign of the bottom waviness ranged from-1,3027 to 1.6099.Chapter 4:The Influence of Fabric Properties and Pleated Ratio on Skirt Appearance.Through the one-way analysis of variance(ANOVA),it is found that there are significant differences in the appearance of the pleated skirts with different pleat ratios.The correlation between the performance of the pleated skirts and the performance of the pleated skirt at different pleating ratios is also analyzed.Based on the regression analysis,Pleated skirt appearance modeling evaluation of the main factors of the objective regression model and found that:the more drape,the more rigid feel of the fabric made of pleated skirts,the more fluffy body,the greater the proportion of smoked,smock skirts The wider the body fluffy;the more rigid the fabric the worse,the less easy to bend,which made the pleated skirt waist fold less inconsistent corrugation width,the more uneven arrangement,and the proportion of shirking 1:1.5 pleated Skirt waist uniform the most uniform deformation;the better the deformation resistance of the fabric made pleated skirt the less the number of ripples,the lower the depth of ripples,the greater the proportion of smoked,the more the number of the bottom of the ripples,ripples The deeper the depth.Finally,the optimal chinking proportion was selected based on the predicted value of the overall aesthetic appearance of the pleated skirt.Taking the performance of the fabric as the explanatory variable and the optimal chinking ratio as the explanatory variable,the optimal pumping of the chiffon skirt based on the fabric performance was established According to the Logit regression analysis and prediction model of pleat proportion,it is found that the better the drape,the softer the easily deformable fabric,the higher the probability of the best pleating ratio of the pleated skirt is 1:1;the more firm and difficult to deform,the worse the drape Of the fabric pleated skirt the best proportion of 1:2 pleating the greater the probability;drape and soft moderate degree of pleated pleated skirt pleated skirt ratio of 1:1.5 the greater the chance.Chapter 5:Summary and outlook.The subject summarized the research contents of the full text,put forward the limitations of this paper,and prospects and suggestions on the future appearance of the pleated skirt and fabric properties. |
